@ITMSuhl The problem isn't the distribution but the updates are taking far longer than usual. Normally a server is up and running again within an hour, now there are systems that are busy for > 4 hours. especially the reboots are taking much longer.

Disabled all F-secure services on one system. Downloaded all updates on both systems, same set, and started the update process. The Server with F-secure disabled is ready to go and rebooted within the hour (43 minutes). The second system is still busy "Getting Windows Ready, Don't turn off your computer" after 107 minutes.

Yes, checked that before i started the updates.I'm letting this rest now, monday is our production patching, so i'm not going to change any more and just disable f-secure on all servers.After that i will open a case with F-secure.

I just heard from our Desktop team that they also experience problems with Windows 10 clients.
